family has a square driveway with an area of 210.25 m exponent 2. Find the perimeter of the driveway. Round your answer to the n
miv72 [106K]

Answer:

191 ft.

Step-by-step explanation:

From the question given above, the following data were obtained:

Area (A) of square = 210.25 m²

Perimeter (P) =?

Next, we shall determine the length of each side of the drive way. This can be obtained as follow:

Area (A) of square = 210.25 m²

Length (L) =?

Area of a square is given by:

A = L²

210.25 = L²

Take the square root of both side

L = √210.25

L = 14.5 m

Thus, the length of each side of the drive way 14.5 m

Next, we shall determine the perimeter of the drive way. This can be obtained as follow:

Length (L) = 14.5 m

Perimeter (P) of square =?

Perimeter of a square is given by:

P = 4L

P = 4 × 14.5

P = 58 m

Finally, we shall convert 58 m to foot. This can be obtained as follow:

1 m = 3.3 ft

Therefore,

58 m = 58 m × 3.3 ft / 1 m

58 m = 191.4 ft

58 m = 191 ft

Thus, 58 m is equivalent to 191 ft.

Therefore, the perimeter of the drive way is 191 ft.
